DAEHAN Orifice Plate With Flange

DAEHAN Paddle-Type Orifice Plates are used with Orifice Flange

Unions.All outer diameters of the plates are machined, providing auniformlycircular disc. This results in a high degree of concentricity ofthe Orifice boreand the plate outer diameter. Next, handles are carefullywelded on. Theplates are then sanded in special machines to aprescribed finish. Bankplates and plates with popular bore size arestocked continuously. Eachplate is stamped on its handle with linesize, flange rating, Orifice bore andplate material. DAEHAN maintains astock in Type 304 and 316 StainlessSteel in standard thickness. Othersize and materials are available onrequest.

1) Concentric Edge

The bore and bevel is the standard of limiting the plate edge thickness.Thebevel is machined on a 45 angle to the desired edge thickness.Unlessotherwise specified, plates will be bevelled to 1/50 of the lineI.D. or 1/8of the Orifice bore, minimum governing.

2) Eccentric

Eccentrically bored plates are plates with the Orifice offcenter,oreccentric, as opposed to concentric. The bore of theeccentric Orificenormally is inscribed in a circle with is 98%of the pipe diameter, sothat solids or slurries may passthrough, Eccentric Orifice plates areused in many industriesincluding heavy and light chemicals, steel,paper, atomic andpetrochemicals.

3) Segmental

Segmentally bore Orifice plates are provided formeasurements wheresolides are entrained in a gas or liquidflow stream. The circular portionof the bore is inscribedwithin a circle which is normally 98% of thepipe diameter.The segmental opening may be placed either at the toporbottom of the pipe. Industries using these bores includesewagetreatment, steel, chemical, water conditioning, paper,andpetrochemical.

4) Advantage of orifice

- Low cost

- Easy to installation

- Availability to comprehensive with standard (ISO 5167-2)

- No requirement for calibration – Value of the discharge coefficient from the standard
